FOLDING BOX.

Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed July 21, 1913. Serial No. 780,199.

To all whom it may concern Be it known that I, HERBERT A. Fmcu, a

citizen of the United. States of America,

and a resident of Cherokee, Cherokee county, Iowa, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification.

My invention relates to folding boxes, and the objects of my improvements are these: First,,to form a box of a connective plurality of parts preferably stamped out in the first instance in one piece from suitable material or of corresponding parts susceptible of being connected together with the use of other fastening-means, and'the peculiar foldings and engagements of certain of the parts upon and with each other; second, the securing together and reinforcing of the angles and corners of the box in such a manner as to not only greatly strengthen the structure, but also prevent displacement of parts of the box while in use; third, to cause certain parts of the structure to bear against other parts thereof when brought together into mutual engagement at or adj acentto the angles of the box, so that one of said fastening-means is reinforced and secured by means of the other fasteningmeans; fourth, to provide a folding structure, which, when brought together shortly, resist, not only collapsing forces exercised from the outside thereof, but will also have its parts held more securely together by means of the contents of the box bearing against certain parts thereof; fifth, to arrange such a folding cover adapted to enwrap the top and certain of the angles of the box such as will more completely pro tect the contents of the box when filled; sixth, to arrange the foldingflaps and parts of the box in such a manner as to permit of a plurality of compartments being established in the box, in which articles may be segregated from each other. These objects I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which i Figure 1 is a plan view of a piece of material which is cut and scored to produce a blank embodying some of the features of my invention. Fig. 2 is a perspective view illustrating the blank of Fig. 1 in a partly folded.

position to produce the box in the first stage of assembling the folded parts together.-

.Fig. 3 is .a plan, view of the blank in a further stage of its folding, showing it in its completely folded condition, except for the enwrapping of the coverflaps thereover. Fig. 4 is a perspective view of the box in its completely folded condition. Fig. 5 is a broken detail perspective view of the part of the folded blank, showing the cooperatingangle securing-means. Fig. 6 is a plan view ofa piece of material which is cut and scored to produce a blank embodying slightly varied and additional features of my invention. Fig. 7 is a plan View of the blank of Fig. 6, in a partially folded condition, in which the end walls only of the lowermost compartment are connected together. Fig. 8 is an enlarged perspective view of the blank of liig. 6, showing it in a secondary stage of folding. Fig. 9 is a plan view similar .to Fig. 7 but showing a still more advanced stage of the folding, in which the lowermost compartment has been completely formed and the uppermost compartment parts established before the cover flaps have been folded thereover. Similar numerals of reference and characters of reference denote corresponding parts throughout the several views.

Referring first to Figs. 1 to 5, inclusive,

which show the primary and simplest form vof my invention, Fig. 1 illustrates a blank formed .of a piece of paper-stock or other I suitable material, which is cut and scored suitably, preliminary to being folded 1nto box form. Said blank has cuts or incisions, a a and?) b. It also has scorings or creases to c7, 0 d rifle e, f f, z 11, 1?, i 70 in, W, 70 g and h. The blank consists of the bottom it, the side-folds 2 and 3, and the end-folds [18 and 19. The end-fold 19 has a cover-fold '20, which latter has an end-flap 21. The

side-fold .2 has' on opposite ends the end-.

flaps 4: and 5, which are respectively furnished with the tabs 8 and 9. The other side-fold 3 has on its opposite ends, likewise, the flaps 6 and 7, which are respectively furnished with the end-tabs 12 and 13. The side-flap 2 also has a top-flap 10, having on its opposite ends the tabs 14 and .515, respectively. The other side-fold 3 has a like top-flap 11, whose opposite ends are Supplied with the tabs 16 and 17, respectively. It will be seen that the bottom 1 is in one continuous piece with the end-folds :18 and-withthe cover-flap, composed of the parts 19, 20 and 21. The opposltelylocated side-folds 2 and 3, with their respectlve tabs formed and afterward connected together by any suitable means to provide flexible joints at their respective proper places to form a receptacle such as is contemplatedin this invention. a

The tabs 14, 16 and 17 are shown as having one angle of each removed to form a tongue-shaped piece in each case for convenience, although they may all be formed similar to the tab 15, which is oblong in sha e. The other tabs, 8, 9,12 and 13 are ma e in a narrowed form projected from the middle of the end of the flaps 4, 5, 6v and 7, for the purpose of being fittingly received within the slots Z Z, on and m formed respectively in the middle of the. creases 11 i k and Z0".

Referring to Figs. 2 and 3, which represent different stages of the rocess of folding the partsof the blank into a box, Fig. 2 shows the side-folds 2 and 3, bent upward at angles to the bottom 1, along the creases c, with the flaps 4 and 7 bent on the creases i and k inwardly to have their end tabs 8 and 13 lie along the abutting inner-walls of the said folds 2 and3, respectively. The other flaps 5 and 6 are thenbrou ht over to lie upon the outside of the said aps 7 and '4, respectively, with their end-tabs '9 and 12 respectively passed through the slots m and Z, to lie along the inner walls'of said folds 2 and 3. c V

' nowto Figs."'3 and.-5,' the top Referrindg flaps 10 an 1 are next bent over horizontally tabs then being pushed downwardlywhen the topfolds 11 are bent over horizontally.

to lie in juxtaposition to the abutting flaps. 7 and 4, respectively, with the edges of saidtabs which lie along the incisions b and b contacting with the tabs 8 9 12; and 13, which lie between them and te said "sidefolds 2] and 3, the partially folded box is then in a position presenting the form shown in Fig. 3, and when the end-iiap 18 and the combined endand cover-flaps 19, 20 and 21 are carried up over the ends 5 and 6, "and with the part 20 lying horizontally upon the top-folds 10 and 11, the box is in its closed condition shown in Fig. 4." Any suitable fastening-means may then be employed to secure said cover parts 19, 2'0 and 21 upon the other parts of t e box. Special parts into more intimate connection. When 2 2", .2 2' It also attention is invited to Fig. 5, which illustrates the angle connections and reinforce- 'ments of the box. It will be seen that the end-parts 5 and 7 form a double wall, while the side-fold 3 and the overlying tab 9 form a structure of double thickness at the angle of the box, While the in-tiirned tab 17 supplements each of these reinforced parts, at the same time, looking the tab 9 against the inner wall of the part 3. It is obvious that when the box is closed and covered that any exteriorly applied force will meet with a maximum of resistance at these angles, while at the same time forcing the interlocked the box is filled, the, contents will bear .against the parts described at the angles,

and tend to hold them in close contact preventing displacement thereof. The topfolds 10 and 11 offer added reinforcements to the longitudinal upper angles of the box and to the upper corners against any operating force, while acting as trusses to the side walls 2 and 3. The cover part 20, with the end-parts 18, 19 and 21 reinforce the ends and top of the box, and taken together, make a very rigid structure from the lightest material.

The folding-box illustrated in Figs. 1 to 4, inclusive, is the simplest basic form of my Invention, but I have shown in Figs. 6 to 9, inclusive, a folding box, which comprises the same principles of construction and arrangement, with some added parts, adapted to cooperate with the other parts to supply two compartments therein, adapted to receive and hold separated contents. The blank shown in-Fi 6 has the incisions y y,

%1LS the scorings or creases j, n n, s s,t t, a u, ww', mac, 0, q and r. The part 22 forms the bottom of the box, and lies in alinement with the oppositely directed folding parts 46, 47 and 48, K extending from'the left-hand crease j and the parts .49, 50 and 51 extending from the right-hand crease At right angles to the strip composed of said parts are the sidefolds or parts 23 and 25, extending from the upper crease j, and the parts 24 and 26 exr tending from the lower crease j. Tl1e s1dcfold 23 has on its opposite ends the pairs of -fiaps'31 and 35, and 33 and 37, respectively,

said flaps having respectively at their ends the tabs 32, 36, 34 and 38. The top-flap 25 of the part 23 has on oppositeends the truncated tabs 27 and 28, respectively, and the other top-flap 26 on the part 24 has like truncated oppositely-disposed tabs 29 and 30. The side-fold '24 also has like oppor siteIy-disposed pairs of similar flaps 42 and 39, and 44 and 58, which have their tabs 43, 40, and 45 and 41, respectively. I have provided middle slots 52, 53, 54, 55, 56 and 57 along or adjacent tothe creases u, m, t t

u and 10', adapted to receive certa n of the tioned.

46, 47 and 48 are shown as carried partially over the lowermost compartment formed as above described and illustrated, to overhang same, and the process of finishing the lowermost compartment is completed by merely carrying said parts over until the middle fold 47 forms a cover for said lowermost compartment, with the folds 46 and 48 respectively covering the end-pieces 39 and 33, respectively.

In order to form a second or superposed compartment, the upper end-flaps 35 and 4:2, and 87 and 44 are folded inwardly to overlie each other respectively in pairs in. a similar way to the method for arranging the other end-flaps 31 and 39, and 33'and 58v lying thereunder. The tabs 38 and 43 are pushed through the slots 56 and 52, respectively, and then the top-flaps 25 and 26 are folded over toward each other horizontally with their end-tabs 27 and 28 and 29 and 30, bent over at right angles and pushed down into the'box to engage the end-tabs 36, 38, 43 and 45, and lock the same in place in a similar way to that shown in Fig. 5. The endfold 4:9 is then bent up on the crease j to overlie the abutting end of the two compartments and the top part 50 brought over to close the top of the uppermost compartment, with the end part 51 brought down upon the opposite end-wall of the box. Any suitable means may then be used to secure the cover upon the box, as previously menlt will be seen that the last device shown and described is simply the same as the first described device, with the mere addition of the compartment producing means. The angles of the box thus formed are reinforced and secured in the same way, and the box is throughout formed and strengthened in the same manner as that shown in Figs. 1 to 5, inclusive.

It will be obvious that each of the angles and corners of my box are so overlaid with other parts when folded together that the contents are prevented from leaking out. It

is also obvious that the two compartment boxes described may be variously modified and other compartments added and connected together in a like manner, without departing from the principle of my inven tion.
